[0041] Embodiment one

[0042] In combination Figs. 1 to 3As shown, the track assembly provided by the embodiment is arranged on the photovoltaic cleaning device, and the photovoltaic cleaning device is used for cleaning the photovoltaic panel. When the photovoltaic panel is cleaned, the track assembly can enable the photovoltaic cleaning device to cross the misaligned photovoltaic panel and ensure the running stability when cleaning on the misaligned photovoltaic panel, thereby reducing the probability of damage to the photovoltaic panel. Specifically, the track assembly comprises a walking assembly 100 and a floating assembly 200. The walking assembly 100 comprises a driving wheel 110, a driven wheel 120, a driving member 130, a mounting base plate 140, and a transmission belt 150. The driving wheel 110 and the driven wheel 120 are arranged on the mounting base plate 140 in the X direction and are spaced apart. The driving wheel 110 is drivingly connected to the output shaft of the driving member 130. The driven wheel 120 is drivingly connected to the driving wheel 110 through the transmission belt 150. The floating assembly 200 comprises a floating connecting member 210 and a floating wheel 220. The floating connecting member 210 is rotatably connected to the mounting base plate 140 and is located between the driving wheel 110 and the driven wheel 120. The floating wheel 220 is rotatably connected to the floating connecting member 210 and is in rolling engagement with one side of the transmission belt 150 close to the photovoltaic panel. When the walking assembly 100 moves on the photovoltaic panel, the floating connecting member 210 can rotate relative to the mounting base plate 140.

[0043] Since the floating wheel 220 is rotatably connected to the mounting base plate 140 through the floating connecting member 210. Therefore, when the photovoltaic cleaning device moves on the photovoltaic panel and cleans the photovoltaic panel, it passes through the misaligned photovoltaic panel. According to the different misalignment degrees between the photovoltaic panels, the floating connecting member 210 rotates relative to the mounting base plate 140 to change the rolling engagement area of the floating wheel 220 with the transmission belt 150, thereby adaptively changing the position and inclination angle of the transmission belt 150 close to the photovoltaic panel, so as to assist the track assembly to drive the photovoltaic cleaning device to cross the obstacle, thereby ensuring the running stability of the track assembly. In the embodiment, the driving wheel 110 and the driven wheel 120 are both arranged as gears. Specifically, the outer peripheral wall of the driving wheel 110 and the driven wheel 120 is provided with transmission teeth, and the inner wall of the transmission belt 150 is correspondingly provided with transmission splines. With the operation of the driving member 130, the driving wheel 110 and the driven wheel 120 are drivingly connected through the transmission teeth and the transmission splines at the corresponding positions, thereby further improving the transmission effect. In addition, in the embodiment, the driving member 130 is arranged as a reversible motor. During the cleaning process, with the forward rotation or reverse rotation of the reversible motor, the track assembly can move forward or backward, thereby driving the photovoltaic cleaning device to move forward or backward in the X direction, so as to further improve the cleaning effect.

[0044] Specifically, two floating wheels 220 are provided, and the floating connecting member 210 is provided in a plate shape. The two floating wheels 220 are oppositely arranged at two ends of the floating connecting member 210 along the X direction, and are symmetrically arranged about the connecting point of the floating connecting member 210 and the mounting base plate 140. The connecting point of the floating connecting member 210 and the mounting base plate 140 is higher than the center line of the two floating wheels 220. When the track assembly crosses an obstacle, the floating connecting member 210 rotates relative to the mounting base plate 140, ensuring that at least one floating wheel 220 is in rolling cooperation with the transmission belt 150, thereby assisting the track assembly to cross the obstacle more smoothly. Since the two floating wheels 220 are symmetrically arranged about the connecting point of the floating connecting member 210 and the mounting base plate 140, the track assembly can run smoothly whether it is moving forward or backward. In other embodiments, the arrangement of the floating wheels 220 is not limited to this, and can be appropriately increased or decreased according to actual conditions.

[0045] Preferably, the outer wall of the transmission belt 150 is provided with a limiting groove 151, which extends along the length direction of the transmission belt 150 and can be limited in cooperation with the support cable under the photovoltaic panel. In some scenarios, the photovoltaic panel is laid on the support cable. When the photovoltaic cleaning device moves from the current photovoltaic panel to the next group of photovoltaic panels, the track assembly continues to run. When the track assembly moves away from the current photovoltaic panel, the limiting groove 151 on the transmission belt 150 is limited to the corresponding support cable between the two groups of photovoltaic panels. With the operation of the corresponding driving member 130, the corresponding track assembly moves from the support cable to the next group of photovoltaic panels. During the whole process, the photovoltaic cleaning device does not need to be taken off from the current photovoltaic panel, which ensures the cleaning efficiency and the stability of the continuous operation of the track assembly and the photovoltaic cleaning device on the photovoltaic panel and the support cable.

[0046] In order to further improve the running stability of the track assembly on the photovoltaic panel when the photovoltaic cleaning device cleans the photovoltaic panel, the outer wall of the transmission belt 150 is provided with an anti-skid part in the embodiment. (not shown in the figure). The anti-skid part can be composed of a plurality of anti-skid protrusions or a plurality of anti-skid protrusions arranged at intervals according to actual conditions, which is not limited here.

[0047] Preferably, the track assembly further comprises a tensioning assembly 300 movably arranged on the mounting base plate 140 along the X direction and in transmission connection with the driven wheel 120. As the transmission belt 150 is used for a long time, the transmission belt 150 may be loose. Since the tensioning assembly 300 is provided, the relative position of the tensioning assembly 300 and the mounting base plate 140 is adjusted in the X direction to change the pressing force of the driven wheel 120 and the transmission belt 150, thereby ensuring the transmission effect between the transmission belt 150 and the driving wheel 110 and the driven wheel 120.

[0048] Specifically, the tensioning assembly 300 comprises a tensioning connecting piece 310 and a tensioning connecting shaft 320, and the mounting base plate 140 is provided with a tensioning hole extending in the X direction in a strip shape; the tensioning connecting piece 310 is fixedly arranged on the mounting base plate 140, and the first end of the tensioning connecting shaft 320 is movably connected to the tensioning connecting piece 310, and the mounting shaft of the driven wheel 120 passes through the tensioning hole and is connected to the tensioning connecting shaft 320. When the transmission belt 150 is loose, the relative position between the tensioning connecting shaft 320 and the mounting base plate 140 is adaptively adjusted in a direction away from the driving wheel 110 until the driven wheel 120 is again tightly abutted against the transmission belt 150, so as to ensure the transmission effect between the driving wheel 110 and the driven wheel 120.

[0049] Further, the tensioning assembly 300 further comprises an adjusting plate 330 and an adjusting connecting piece 340, the adjusting plate 330 is movably connected to the mounting base plate 140 in the X direction through the adjusting connecting piece 340, the mounting shaft of the driven wheel 120 is fixedly connected to the adjusting plate 330, and the second end of the tensioning connecting shaft 320 is drivingly connected to the adjusting plate 330.

[0050] In combination Fig. 2 As shown, the adjusting plate 330 is provided with two connecting through holes 331 spaced apart in the height direction, both of which extend in the X direction, the adjusting connecting piece 340 passes through the corresponding connecting through hole 331 and is connected to the mounting base plate 140, so that the adjusting plate 330 is connected to the mounting base plate 140, and the mounting shaft of the driven wheel 120 is fixedly connected to the adjusting plate 330; in this way, the mounting stability of the driven wheel 120 is improved, and the self-displacement of the driven wheel 120 in the height direction is avoided, so as to ensure the running stability of the track assembly. The second end of the tensioning connecting shaft 320 is drivingly connected to the adjusting plate 330, when it is necessary to change the abutting force of the driven wheel 120 against the transmission belt 150, the tensioning connecting shaft 320 drives the adjusting plate 330 to move in the X direction, and the adjusting plate 330 cooperates with the two adjusting connecting pieces 340 to ensure the running stability of the adjusting plate 330 and the driven wheel 120 during the tensioning process.

[0051] In some other embodiments, in order to improve the stability when changing the abutting force of the driven wheel 120 against the transmission belt 150, a tensioning driving motor is arranged on the mounting base plate 140, and the tensioning connecting shaft 320 is drivingly connected to the motor shaft of the tensioning driving motor.

[0052] Embodiment two

[0053] In combination Fig. 3As shown, the photovoltaic cleaning device comprises a rack 400, a cleaning assembly 500, an auxiliary adjusting assembly 600 and a track assembly; the track assembly is provided with two groups, the two groups of track assemblies are relatively spaced apart along the Y direction and arranged on the rack 400, the auxiliary adjusting assembly 600 is provided with multiple groups, the multiple groups of auxiliary adjusting assemblies 600 are relatively independently arranged, and the auxiliary adjusting assembly 600 is movably arranged on the two support rods 410 arranged along the Y direction of the rack 400; when the photovoltaic cleaning device moves on the photovoltaic panel, the auxiliary adjusting assembly 600 can be self-adaptively lifted relative to the support rod 410.

[0054] Since the multiple groups of auxiliary adjusting assemblies 600 rotatably arranged on the rack 400 are independent of each other, when the photovoltaic cleaning device moves on the photovoltaic panel and cleans the photovoltaic panel, when passing through the misaligned photovoltaic panel, the multiple groups of auxiliary adjusting assemblies 600 are self-adaptively rotated in the forward or reverse direction relative to the rack 400 according to the actual situation, in this way, on the one hand, a part of the vibration of the rack 400 or the track assembly caused by the misalignment of the photovoltaic panel is offset, thereby reducing the probability of damage to the photovoltaic panel; on the other hand, it avoids the situation that the other auxiliary adjusting assemblies 600 and the track assembly are partially or entirely suspended due to the large rotation of one of the auxiliary adjusting assemblies 600, and the contact area with the photovoltaic panel is reduced, thereby maximizing the running stability of the photovoltaic cleaning device when cleaning the misaligned photovoltaic panel. The number of auxiliary adjusting assemblies 600 is not limited, and can be set according to actual needs.

[0055] Taking one of the auxiliary adjusting assemblies 600 as an example, the working principle thereof is described in detail. Specifically, each auxiliary adjusting assembly 600 comprises an adjusting shaft 610, an adjusting wheel 620 and an adjusting spring 630; the first end of the adjusting shaft 610 is rotatably connected to the corresponding support rod 410, the adjusting wheel 620 is rotatably arranged at the second end of the adjusting shaft 610, and the two ends of the adjusting spring 630 are respectively connected to the middle part of the adjusting shaft 610 and the corresponding support rod 410.

[0056] When the photovoltaic cleaning device passes through the misaligned photovoltaic panel, the rack 400 moves away from the photovoltaic panel under the impact force while the track assembly drives the photovoltaic cleaning device to move forward, at this time the adjusting spring 630 is compressed to offset a part of the vibration and weaken the tendency of the whole rack 400 to move away from the photovoltaic panel, thereby achieving the purpose of shock absorption. When the photovoltaic cleaning device has crossed the obstacle, at this time the adjusting spring 630 is no longer under the impact force, the adjusting spring 630 returns to its original state, thereby pushing to rotate towards the photovoltaic panel until the adjusting shaft 610 returns to its original state, so as to ensure the running stability of the photovoltaic cleaning device on the non-misaligned photovoltaic panel.

[0057] Preferably, the auxiliary adjusting assembly 600 further comprises a first limiting rod and a second limiting rod, a first end of the first limiting rod is rotationally connected to the support rod 410, and a first end of the second limiting rod is rotationally connected to a middle portion of the adjusting shaft 610, and two ends of the adjusting spring 630 are fixedly arranged at the middle portion of the first limiting rod and the middle portion of the second limiting rod respectively.

[0058] Specifically, the middle portions of the second limiting rod and the first limiting rod are both provided with limiting baffles, the first end of the adjusting spring 630 is sleeved on the second end of the second limiting rod and abuts against the limiting baffle arranged on the second limiting rod, and the second end of the adjusting spring 630 is sleeved on the second end of the first limiting rod and abuts against the limiting baffle arranged on the first limiting rod. In the process of compression or self-rebound of the adjusting spring 630, both the limiting rods can be adaptively rotated to ensure the expansion and contraction effect of the adjusting spring 630 and avoid the bending of the middle portion of the adjusting spring 630 in the expansion and contraction process of the adjusting spring 630. Further, the second end of the first limiting rod is provided in a cylindrical shape, and the second end of the second limiting rod is movably inserted into the second end of the first limiting rod. The middle portion of the second limiting rod is provided with a limiting piece (not shown in the figure), the limiting piece is arranged close to the limiting baffle on the second limiting rod, and the second end of the first limiting rod is correspondingly provided with an auxiliary limiting portion, when the second end of the second limiting rod is movably inserted into the second end of the first limiting rod, the limiting piece and the auxiliary limiting portion are in sliding limiting cooperation. By movably inserting the second end of the second limiting rod into the second end of the first limiting rod, the expansion and contraction path of the adjusting spring 630 is limited in the expansion and contraction process of the adjusting spring 630, and the bending of the middle portion of the adjusting spring 630 or the situation that the adjusting spring 630 is separated from the first limiting rod or the second limiting rod due to excessive compression of the adjusting spring 630 is avoided, so that the damping effect is ensured and the running stability is further improved. By sliding limiting cooperation of the limiting piece and the auxiliary limiting portion, the relative position of the first limiting rod or the second limiting rod is limited, and in the operation process of the photovoltaic cleaning device, the first limiting rod and the second limiting rod are prevented from being separated, so that the relative position of the adjusting spring 630 is limited.

[0059] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not a limitation on the embodiments of the utility model. For ordinary skilled in the art, various obvious changes, re-adjustment and replacement can be made without departing from the protection scope of the utility model.
